I am working on a patch to improve stability of suspend (and resume) on systems where an interrupt line (legacy PCI) is shared by multiple devices. If you have such a system and you experience hangs during suspend or resume, could you please test the patch? It's easy to check if you have shared interrupt. For example, you can run devinfo -u and check 'Interrupt request lines' of the output for any repeating numbers. I would also appreciate any reviews of the change. Especially, because it introduces new methods to the bus interface. I would like to ensure that the new methods are reasonable. The change is here: https://reviews.freebsd.org/D15755 Thank you. -- Andriy Gapon
